LONDON -- Britain's Foreign Secretary William Hague on Monday urged Ecuador to quickly resume negotiations over the fate of WikiLeaks founder Julian Assange.

Assange, who is seeking to avoid extradition to Sweden for questioning over sex crimes allegations, has been sheltering inside Ecuador's Embassy in London -- beyond the reach of British police -- since June 19.

Ecuador has offered Assange asylum, but he will be arrested if he sets foot outside the embassy.

Hague said that Ecuador should resume talks "as early as possible." "Our two countries should be able to find a diplomatic solution," Hague wrote in a statement.

Assange claims the Swedish sex case is merely the opening gambit in a plot to make him stand trial in the United States over his work with WikiLeaks, which has published large troves of secret U.S. documents. Sweden and Washington reject those claims.

Also Monday, German lawmaker Sevim Dagdelen said she visited Assange inside the embassy to send him a message of solidarity from supporters in her country. She added that she planned to pursue meetings with British and Swedish diplomats in Berlin to discuss a solution to the case.
